':::' calls which should be '::':
‘base:::call’ ‘base:::importIntoEnv’ ‘base:::lockEnvironment’
‘base:::match.call’ ‘base:::print.default’ ‘base:::print.function’
‘tools:::Rd2txt’ ‘utils:::?’
See the note in ?`:::` about the use of this operator.
Unexported objects imported by ':::' calls:
‘tools:::.Rd_get_metadata’ ‘tools:::.get_package_metadata’
‘tools:::.install_package_Rd_indices’
‘tools:::.install_package_Rd_objects’
‘tools:::.install_package_description’
‘tools:::.install_package_namespace_info’ ‘tools:::.read_description’

‘tools:::RdTags’ ‘tools:::fetchRdDB’ ‘tools:::makeLazyLoadDB’
‘tools:::prepare_Rd’
See the note in ?`:::` about the use of this operator.
There are ::: calls to the package's namespace in its code. A package
almost never needs to use ::: for its own objects:
‘Save’ ‘body.print.function’ ‘cd’ ‘rbind.data.frame’
‘search.task.trees’ ‘untetherBalloon’
